Clinical Approach
I work deeply and extensively with highly internalized, masked, and compensated autism, particularly in adults whose Autistic/ADHD/AuDHD traits may not fit stereotypical presentations based on the external gaze. Many of the individuals I work with have spent years, if not decades, developing sophisticated ways of adapting, masking, and compensating—often without realizing how much effort those strategies require—so a major focus of my assessments is understanding the internal autistic, ADHD, and AuDHD experience, not just externally observable behaviors. This is especially important because autism and ADHD frequently overlap with, or are obscured by, complex trauma, anxiety, perfectionism, people-pleasing, compliance conditioning, and longstanding compensatory adaptations, making it essential to carefully understand how these factors interact rather than making assumptions based on surface-level traits alone.
Unfortunately, many adults continue to be overlooked or dismissed because traditional diagnostic models were developed around more externally visible presentations, causing clinicians to miss internal experiences such as chronic social monitoring, camouflaging, sensory overwhelm, identity confusion secondary to navigating ableist paradigms, exhaustion from masking, or a deeply intuitive lifelong sense of being different without understanding why. My approach is grounded in the understanding that autism and ADHD are not simply collections of outward behaviors, but neurodevelopmental ways of experiencing and interacting with the world that deserve thoughtful, individualized evaluation.
My focus is specifically on understanding neurodevelopmental profiles, developmental history, internal experience, diagnostic presentation, compensatory strategies, masking and camouflaging, and the complex interaction among neurodevelopmental and psychological factors. My reports elucidate, in a highly personalized and individualized manner, the interplay of various dynamic processes including the active interplay between differential diagnostics. None of those domains exists in a vacuum, and the meaning of any individual finding depends on its relationship to the person's broader profile, history, and context.
Multiple structured diagnostic interviews and psychometrics are integrated with the individual's history, conditioning, schemas, executive functioning, impulse control domains and subdomains, and their correlation and interplay with one's emotional regulation system, interoception profile, monotropism profile, environment, attachment, exposure, and so many other aspects of cognitive, emotional, sensory, social processing and interpersonal and societal conditioning and programming. The assessment is therefore not about generating a series of “yes” or “no” answers; it is about understanding the configuration and interaction of the person's entire neurodevelopmental profile. In addition to diagnostic clarification, my assessments are a process that goes beyond the diagnostic code into a wider panoramic landscape which incorporates various elements of one's lived experience and personhood in a manner that moves into vicinites similar to a neurotype GPS location, fingerprint, or DNA: no single measure can provide that degree of specificity, but the convergence of multiple carefully considered data points can create an increasingly precise picture of where someone is situated, what terrain they have been navigating, and how they came to be there.
A central part of my work is differential formulation. I am not simply asking whether a traits and/or symptoms are present; I am asking what it represents, what function it serves, what mechanism is driving it, how it developed, and how it interacts with everything else in that person's system. That may mean carefully differentiating complex trauma from neurodevelopmental differences, anxiety from autistic overwhelm, depression from the consequences of chronic masking or burnout, OCD from recursive autistic thought processing, repetitive behaviors from compulsive rituals, intolerance for ambiguity loops and vagueness from other forms of anxiety or rigidity, or ADHD-related executive dysfunction from difficulties arising through other mechanisms. It may also mean considering autism, ADHD, AuDHD, broader autism phenotype characteristics, and the ways these may interact with trauma, anxiety, perfectionism, people-pleasing, compliance conditioning, and longstanding compensatory adaptations.
Two people can present with what looks externally like the same behavior while having entirely different underlying mechanisms. Likewise, a behavior that appears pathological when viewed in isolation may have a very different meaning when understood within the context of autism, ADHD, trauma, anxiety, sensory processing, executive functioning, emotional regulation, or accumulated experiences of navigating environments that were not designed around their neurology. This is why I am particularly attentive to internal experiences that may not be visible from the outside, including chronic social monitoring, camouflaging, sensory overwhelm, identity confusion secondary to navigating ableist paradigms, exhaustion from masking, and a deeply intuitive lifelong sense of being different without understanding why.
I also place client self-determination above all else. My role is not to tell a client who they are, impose an identity upon them, or require them to accept a particular diagnostic formulation. My responsibility is to provide the most careful, comprehensive, clinically responsible information I can, explain my clinical and diagnostic reasoning transparently, and support the client in making their own informed decisions about what that information means for them.
That having been said, due to the multitude of clients I have worked with who have suffered the effects of diagnostic overshadowing, I would be remiss to not give voice to my recommendation to consider assessment for both Autism and ADHD when the clinical picture raises meaningful questions about both, rather than prematurely narrowing the inquiry to one. There can be a very complex interplay between neurodivergent assimilation, masking, camouflaging and compensatory mechanisms as well as aspects of neurodivergent experience that can be internalized and/or channeled into socially rewarded outlets which can make the internal cost slower to become perceptible (e.g. masked and internalized AFAB hyperactive type ADHD is frequently missed because it doesn't look like a boy jumping off the bannisters).
I have seen firsthand how long diagnostic overshadowing can persist when one diagnosis, presenting problem, or clinical narrative effectively obscures another aspect of a person's neurodevelopmental profile. People can spend years or decades understanding themselves through an incomplete framework, only seeing part of the picture, or interpreting longstanding neurodevelopmental differences as anxiety, trauma, personal failure, characterological difficulty, or something else entirely. Recommending consideration of both assessments is therefore not about assuming that Autism and ADHD always travel together. Rather, it is about reducing the possibility that an important part of the developmental picture will once again be overlooked. Client self-determination is the paramount at Silhouette Psychotherapy and clients will always remain the ultimate decision-makers about whether to pursue assessment, what questions they want answered, what conclusions they find meaningful, and how they choose to use the information. The recommendation that clients consider a particular avenue of assessment is made in response to the adversity that can ensue from diagnostic overshadowing, but is made with full respect for the client's autonomy and final choice.
My reports reflect this same philosophy. Options offered range in length from condensed to comprehensive, from 10-90 pages in length, with various options in regard to depth of detail, including the relevant domains, subdomains, and aspects of a person's profile. Multiple diagnostic interviews are completed alongside a psychometrics battery. The purpose of this depth is to preserve clinically meaningful nuance, protect against the risk of masking causing the externally observable to again overshadow the internal lived experience and reality, and to provide an integrated understanding of how the different pieces of an individual's profile fit together.
For some clients, this level of detail can be extraordinarily meaningful. It can provide language that can assist in self-understanding where there may have been a lifetime of misattunement, misinterpretation and even epistemic overwriting of their self-authority. For clients who have struggled to know how to organize their self-understanding against how they are perceived externally, particularly when there has been longstanding dissonance, this depth of detail can help with the re-contextualization of such dynamics. It can give evidence-based contextualizations for a deeper self-understanding, in regard to one's personal neurotype which is as unique as a fingerprint (if you've met one autistic person, you've met one autistic person, etc.) There is an odd occurrence where it is seemingly easier for most to understand that neurotypicals are each unique from one another, but when it comes to neurodivergence, the baseline default assumption seems to be that shared neurotypes means neurodivergents are all the same. Not so, and the comprehensive reports provide a personalized depth that for many who have experienced self-confusion and consistently experienced others finding them confusion, be medicinal in ways when it comes to self-understanding and identity recontexualization. Clients sometimes find the report gives them words for experiences they have struggled to articulate, connect seemingly disparate aspects of their lives, make previously confusing patterns coherent. It can also create a detailed framework they can return to over time or share with other providers when useful.
For other clients, however, an 80–100-page report can feel overwhelming. More information is not necessarily better for every person, and I respect that different clients have different information-processing needs, preferences, circumstances, and resources. Condensed reports are therefore available both for clients who would benefit from a more concise and accessible formulation and to provide variance and flexibility in choice. These various options provide agency and choice to clients regarding which report type would feel the most meaningful to them at the time in their life that they are reaching out. Often clients may initially seek and obtain diagnostic clarification and then return later for the microscope version, in order to gain more understanding of their own exact and precise profile to assist with enhancing their quality of life or answering further unanswered questions. The goal is to provide options that respect client preference and information-processing needs while maintaining the same underlying commitment to careful clinical reasoning across report types.
Equal amounts of rigorous clinical synthesis and integration go into both the condensed and comprehensive reports - the difference is limited to the length and detail of the report, as opposed to the formulation process. The length of both report types are reflections of the depth and breadth of the integration and they also transparently delineate my clinical and diagnostic rationale so the client receives an abundance of information about the findings, in addition to diagnostic clarification. The formulations (particularly the comprehensive reports, but both - just to different extents) make clear how the psychometrics, diagnostic interviews, collateral information, developmental history, clinical presentation, contextual factors, and broader profile converge, where they do not converge, where uncertainty remains, and why a particular formulation best accounts for the available information.
Should the person being assessed have a psychotherapist they are working with, I want clinicians to have a formulation that is sufficiently nuanced to be clinically useful and defensible, while clients have an explanation that is sufficiently compassionate, understandable, and individualized to feel true to their lived experience. At Silhouette Psychotherapy, we do not pathologize neurodivergence. We offer assessment services in the spirit of seeking to understand the person's neurodevelopmental profile as accurately and comprehensively as possible while honoring the complexity of the person behind the data. In the assessment process, I strive to create an experience where clients feel understood within the full context of their lived experience and where questions about autism and ADHD can be explored with curiosity, nuance, and care.
In this area of high intersectionality that is filled with critical nuance and the need for skillful discernment regarding complexity, the condensed reports, while abbreviated, do not overstep into irresponsible amounts of compression into false binaries, etc. They are shortened but they as well contain and transmit the clinical reasoning for the final diagnostic formulation, just with less depth of detail about the person's full profile or the interaction among developmental history, psychometrics, diagnostic interviews, internal experience, compensatory adaptations, and the various cognitive, emotional, sensory, and social domain, rather than simply announcing a conclusion with no trail to follow during integration work which follows the assessment process.
Ultimately, I want clients to leave with more than a label. I want them to have a coherent, evidence-informed (both objective and subjective evidence matter profoundly in our process) explanation of themselves—one that accounts for their patterns, adaptations, strengths, vulnerabilities, sensory and emotional experiences, cognitive style, and the enormous amount of effort that may have gone into navigating environments that did not naturally fit their neurotype profile. I want the assessment to give both the client and, when appropriate, their clinicians a map: not only a reductive answer yes or no, but a detailed understanding of the terrain they are navigating and the mechanisms that help explain how they experience the world. That balance—rigor without reductionism, affirmation without assumption, complexity without pathologization, and clinical expertise without surrendering client self-determination—is at the center of my neurodevelopmental assessment practice.
